Has anyone seen info about overclocking a PowerBook G4 667 (gigabit ethernet), I have seen them for the 400/500 mhz books, as well as for the DVI models that came out later, I have already found the jumpers, I really just need which ones to remove, and which to bridge with solder to get the various speeds it can run at (a chart would be nice).
Thanks,

Here's the only site of which I'm aware, but it only shows the 100 to 133MHz bus speedbump procedure.
Hmmmmm, I've got a 550, but do I have a 667 GigE MLB in my box o' bits . . . ? :? With both in hand, one could at least get some idea of which jumpers do what. I'm sure the basic principles carry over from the other 'Books for which info is available.
BTW, bookmark Marc Schrier's page for future reference everyone! It's the foremost Mac overclocking page and a great starting point for all such endeavors.

The 667 only has one jumper, at R326, I took a guess, and soldered bridged R265, this gave me 733mhz, and the powerbook ran great for about 5min, then got really unstable, and programs would not launch, I assume it over heated, but the fan never kicked on (perhaps it heated up too fast, or it was something other then the cpu that got hot) I did not keep going to discover anymore speeds as I assume if it does not work a 733mhz, it really won't at 800mhz. I have restored my TiBook back to 667mhz, and it is fine.
btw, I have a photo of the area of the board where the jumpers are if anyone cares to see it.
